Abstract

The invention makes it possible to improve the quality of washing due to the reliable base of products. The pivot points 1sn 18,19 and the side guide 20 are set at an angle to the horizon. In the support guides 18, 19 in the areas of washing and drying and in the pushers 14, cavities are made in which. Additional nozzles for supplying cleaning solution or air are placed, and inclined guides with guide rollers are installed at the inlet and outlet of the machine. The workpiece 5 is first washed in the chamber by means of a contour and 8 directional treatments - this is a general treatment in the sink, and by means of additional nozzles - washing the holes. Then, the drying is carried out in the chamber in the same way and the processed product leaves the car about 8 or A-A yu out of the orienting rollers.

"

The invention relates to the field of cleaning products, namely, equipment for washing and drying various products, in particular, car cylinder blocks.

The purpose of the invention is to improve the quality of cleaning.

Fig. 1 shows parts of a conveyor washer, a longitudinal section in FIG. 2 is a section A-A in FIG. 1; FIGURE - section BB in FIG. 1; figure 4 - section bb In fig.Z; figure 5 - section GG in fig, A; FIG. 6 is a view D of FIG. 2; FIG. 7 is a section E — E of FIG. 6; in fig-, 8 - section Ж-Ж in fig, 1 о

The machine includes a housing 1 consisting of a washing chamber 2 and a drying chamber 3. In the washing chamber 2, a circuit 4 for general washing of the product 5, a circuit 6 for directional end face treatment, mounted for movement in a vertical direction by a hydraulic cylinder 7, and stationary contours 8 for directional processing are placed . All circuits are provided with nozzles 9 for treating holes in the product 5. In the drying chamber 3, a loop 6 is placed for the directional treatment of the ends and the fixed contours 8 for directional treatment, which are designed to compress the holes in the product 5 with air in order to remove residual solution and dirt. top part

chambers 3 above the products are installed duct 10 for sucking the product with air pumped by fan 11. To move the product 5 inside the housing 1 there is a pushing conveyor 12, the conveyor is a long rod 13 with the pushers 14 fixed on it, the bar 13 is mounted on rollers 15 with the possibility of rotational and reciprocating stepping movements by means of hydraulic cylinders 16 and 17 and is intended to move the product 5 from position to position by means of pushers 14, the product is mounted on the supporting directions e 18 and 19 and is fixed by the lateral orienting guideline 20; For more reliable fixing of the product with respect to the longitudinal axis of the conveyor, the guides 18-20 are located at an angle l to the horizon in a plane perpendicular to the longitudinal axis of the conveyor. Thanks to this, item 5 is under action

gravity forces constantly pressing their already machined surface 21 onto the lateral orienting guide 20, thus achieving precise axial positioning of the product 5, which allows increasing the quality of washing the holes in the end surfaces 22 of the product 5 due to more accurate matching of the axes of the holes in the end surfaces 22 and nozzles in the contours 6 of the ends.

The angle ot, chosen experimentally, for cylinder blocks of VAZ cars is 7-10. At smaller values of the angle, the block moves away from the lateral orienting guide 20, and at large values, the resistance to movement of the block increases and difficulties arise during the operation of this machine.

To eliminate dead zones - openings 23 of the plant are closed, with guides 18 and 19, in the latter there are cavities 24 in which additional nozzles 25 are placed for flushing or purging the openings of product 5. The nozzles 25 are connected by channels 26 to the collector 27 for washing solution or compressed air. Cavities 24 are needed to remove contaminated solution or air from the machined holes 23 of the product 5, Dp washing and blowing the holes 28 of the product, made on the end of the block and closed by the pushers 14 of the conveyor 12, in the latter there are holes 29 in which additional nozzles are pressed 30, On the front planes 31 of the pushers 14, acting on the end surfaces 22 of the products during their transportation and processing, around the nozzles 30, cavities 32 are made similar to cavities 24, Supply of washing solution or compressed air from the hinges to the nozzles 30 are made with the help of flexible sleeves 33, which allow movement and rotation of the rod 13,

For a smooth turn of the product at an angle oi when it is loaded and returned to a horizontal position when unloading, at the entrance and exit of the machine, the gadget 34 inclined with the rollers 35 is inclined along the movement of the product 5. The angle of inclination of the axes 36 of the rollers varies from 0 to C6 is proportional to the number of rollers 35 on direction to 34,

Conveyor washing machine works as follows

The product 5, which has been machined, is fed to the alignment rollers 35, moving along which the product 5 inclines and receives a predetermined angle, the angle of inclination of the support guides 18 and 19, and presses the treated surface 21 to the lateral orientation guide 20, Further movement of the product 5 is carried out in an inclined position until the machine leaves the machine. Moving the product 5 is stepped through the push rods 14, Transferring the product 5 in the chamber 2 to the washing section, through nozzles 25 to the bearing directions juls 18 and 19 and corma 29 pushing Leu 14 is supplied with a washing solution for washing the holes 23 and 28,

A common rinsing circuit 4 and a contour 6 of the end treatment of the ends of the article 5 are connected. After that, the pushers 14 move the product 5 to the chamber Sj, where at the drying site through the additional nozzles 25 in the support guides 18 and 19 and the additional nozzles 30 of the pushers 14 feed

in them additional nozzles for supplying washing solution or air, setting up the inlet and outlet of the machine by means of guide rollers with orienting rollers ensures a reliable base, eliminating untreated zones, due to which the quality of washing of products is reduced,

fO Invention allows besides

improving the quality of washing the product holes to eliminate losses associated with defects due to poor-quality washing of the holes, improve the reliability of the work of the assembled products (engines).
